MARTIN DRIVING BOX LUBRICA TOR Filed Nov. 17, 1925 INVENTOR W 1/ m BY W -MW ATTORNEYS Patented Nov. 11, 1-930 UNITED'JSTATES PATENT OFFICE FREDERICK MARTIN, OF BROOKLYN, NEW' YORK, ASSIGNOR TO FRANKLIN RAILWAY SUPPLY COMPANY.- ACORPORATION OF DELAWARE DRiVING-BOX LUBRICATOR v Application filed November 17,1923. Serial No. 675,248.

This invention relates todriving box lubricators. v y y r y p Heretoforein this art, the cellar which contains the grease'cake or other lubricant has heen p1ovided with lugs through which the cellarbolts for securing the cellar to the driving box are passed. In this arrangement it is necessary to remove a cellar bolt in order to take off the end plates for the purpose of repacking the cellar. This operation is sometimes rather diflicult and in addition when 1 i the present time.

the cellar bolt is taken off, the end plate is separated from the cellar and very often lost. This is practically standard equipment at Attempts have also been made to fasten the end plate from the driving box itself, but such arrangements have not been found practical and are open to the same objections above set forth, namely, certain parts must be detached (and maybe lost.) in order to permit of the removal of the end plate.

One of the primary objects of my invention is to provide a construction in which the foregoing difiiculties are obviated.

More specificallyit is an object of my in vention to provide a self-contained driving box cellar and end plate therefor, so constructed and arranged that the lubricator cavity of the cellar may be exposed without detaching the end plate.

Another object is the provision of an arrangement by virtue of which noparts need to be removed in order to move the end plate to expose the cavity of the cellar.

Still another object is to provide what may Fig. 3 is a fragmentary sectionalview iljliistrating certain details of my invention. Referring now to the drawing the reference character A? indicates a typical driving box having a bearing brass 7 for theaxle 8, and the cellar is indicated. as a whole by the reference character B In general, the

cellar is of customaryconstruction and is provided with the usual arcuatc perforated plate 9, the follower plate 10, the spring 11 for pressing the follower plate 10 with its grease cake toward the perforated plate 9, and the dependingeye rods 12 for pulling down the follower platelO when inserting a new grease cake.

At each end of each side of the cellar there is a downwardly projecting lug 13 through which the cellar bolts 1% for connecting the cellar to the drivingbox pass. The open end ofthe" cellar is closed bytheend plate 14 which is loosely but directly carriedby the cellar for swinging movement outward, uncovering the lubricator cavity of the cellar.

For this purpose the. end plate is provided with a downwardly extending clcvis-like lug 15 and the cellar is provided with a pair of spaced lugs 16 which carry a pinl'? passing through the slots 18 in the arms of the clevis lug 15. The ends of the pin may be riveted over as shown; y

The end plate is held in closed position as follows: at each side, the openend of the cellar is provided with the lug 19, the top surface of which is notched or grooved as at 20 so that the lug may he said tobe somewhat hooklike'; and at a lower level the cellar is provided with the similarly shaped lugs 21 which extend upwardly and outwardly from the lugs or ears 13 at such end of the cellar. The

lugs 19 and 21ers offsetvertically and the possible by virtue of the slots 18 before men tioned; Gravity hold the end plate in position in the spaced seats provided by the pairs of lugs 19 and 21, but I prefer to provide means v whereby the end plate is snapped into position and yieldingly held; For this purpose I provide the spring '22, one end of Which passes oyenthe pin, 23 carried by the end plate and the other 'end of which passes over the pin 17. The tension of the spring holds the endplate in position. 7 V To release'the end; plate from engagement 'With the lugs 19 and 21., a toolis inserted into either of the spaces 24 formed between the bottom of the end plate and thelugs 16, and the end plate is pried upwardly a suflicient distance to clear thehooks of the lugs. lVhen' closing the endplate, it rides over the rounded surfaces 25 of the lugs l9 and 21' against the tension of the spring, and snaps into place.

It will be seen from the foregoing thatlirrespective of Whether. or not the spring is'employed, the end plate and the cellar constituteafself-contained structure and that the end platemay bemoved touncover the lubricater cavity Without undoing or detaching any parts whatsoever. If the "locomotive V 7 should be lifted with the Wheels inrplace and should the axle bear on the'end plate, no breakage of the cellar will occur as the pairs of lugs 19 and 21'are inline with the end plate and take the thrust substantially verti- V cally downward. f The otheradvantages Will ".Iclaimvz- I i I 1.
